Contemplating Medium Format - hasselblad

I'm just starting to contemplate getting a medium format digital system like the Hasselblad H4D-40. Anyone have a link to a good article explaining what to consider when making the switch from 35mm full frame digital to medium format?

Purpose is for landscape and studio. Currently shoot a Canon 1Ds MkIII as a frame of reference. Looking for significantly better image quality (tonal range and sharpeness).
